Seed screening device for agricultural sowing

Abstract

The invention discloses a seed screening device for agricultural sowing. The seed screening device comprises a heating box, a horizontal guide rail, a screening cavity, electric heating plates, a stirring paddle and a spiral blade, wherein the horizontal guide rail is fixedly welded to the bottom of the heating box; an inner cavity of the heating box communicates with the inner surface of the horizontal guide rail; and an air compression cavity is fixedly welded to the upper right part of the inner cavity of the heating box. The seed screening device is characterized in that the electric heating plates are fixedly installed at the upper left corner and the two ends of the bottom of the inner cavity of the heating box; a cover plate is connected to the upper edge of the heating box in a clamped mode; an opening is formed in the middle position of the upper part of a screening cavity; and the stirring paddle and the spiral blade are arranged at the middle position of the inner portion ofthe screening cavity. The seed screening device has the functions of quickly screening dried seeds and drying full seeds, saves a large amount of resources in the use process, has simple operation and high working efficiency, and is suitable for popularization and use.

Description

technical field [0001] The invention relates to an agricultural appliance, in particular to a seed screening device for agricultural sowing. Background technique [0002] Seeds are indispensable in agricultural planting. During the seed preservation process, if the surface humidity of the seeds is too high, it will cause mildew and corruption from the outside to the inside, which will affect the sowing of crops. Therefore, in the seed preservation process In the process, the seeds need to be messed up, and the seeds also need to be screened, so as to ensure that the shriveled seeds in the seeds are screened out, thereby improving the germination rate of the seeds; but most of the current seed screening devices do not have the ability to screen the seeds. Drying technology, while the existing seed screening device is complicated to operate, time-consuming and laborious, so we propose a seed screening device for agricultural sowing.
